TO ALL WHOM IT MAY CONCERN;

lBe it known that I, THOMAS B. McCoNAUGHEY, of Newark, in the county of New Castle, and State of Del' aware, have invented certain new anduseful Improvements in Governors; and I do hereby declare that the followingisa full, clear, and exact description thereof, reference being had to the accompanying drawings,

and to the letters of reference marked thereon, which form a part of this specification. In the annex ed drawings, whieh'make a part of this specification- Figure l is a plan view of the hinged arm and driving-pulley of mygovernor,

Figure 2 represents a side elevationef the several devices which form my machine.

Figure 3 is a. plan view of the governor-pulley.

A represents the main wheel, which may b'evputin motion by horse or other power.- B designates a pulley, placed in line with wheel A and fastened to the stanchion C. D represents an arm or lever, forked at both ends, as shown in fig. 1. The upper end of arm D'play-'s on api'vot, which is fastened to\ the frame of my machine. Attached to the said pivot is the rod e, with a hook at its lower end, the use of which will be hereinafter explained.' The lower end of arm D is furnished with driving-pulley g and governor-pulley 7L, and also with the loose pulley j, (see g..1. m represents the rod, to which the brake n is attached. The outer end of said rod is connected by a cord, s, with pulley j,rand the inner end is fastened to the frame, as seen in red dotted lines in fig. V2. E represents a tripping-lever, to the outer Aside of which is fastened the brake F. The inner end of lever E is secured to the frame of my machine. On the upper side of lever E is a staple, t, which is intended to receive the hook on rod c when it is desired to relieve the wheel'A from the pressure of brake F.

I In order to start my machine, it will he necessary, in the rst place, to raise the lever E, so as to relieve the wheel `from thebrake Il', as above described. The power will thc'n be under the control ofthe governor,

`acting on brake n by means of rod m andeord s. `Should the belt H, which drives the govcrnorfshaft, happen to break or come off the wheel A, thc arinD will be left without support at its lower end; and the upper end 'being pivotcd in the manner heretofore described, will, by the downward motion of the lower end of D, disengage the tripping-lever E from the hook e, so that the brake F will come ineon'tact with the circumference of the wheel A, and immediately'farrest its motion.,

Having thus'described my machine, what I claim, and desire to secure by Letters Patent, is*

1. The hinged arm D, iu combination with hook c and trippingglcvcr E, when constructed and operating substantially as set.forth.

2. The governor-pulley 7a, when driven by and combined with pulley g and belt H, in the manner substantially as specified. p

In testimony that I claimythe foregoing as my own, I aix my signature in presence of two witnesses.
